The Devil's Den didn't sample Alice Cooper because there's guitar at 0:07 in No More Mr. Nice Guy, which would've been extremely difficult to filter out without it sounding like so. As for the Nintendo Land sample, it's pretty tiny and very hard to confirm that it was indeed a sample from Nintendo Land and not a synth tone.

This is probably going to sound ridiculous, but I think Skrillex may have sampled Nintendo Land. Yes, Nintendo Land. The invincibility sound effect in Captain Falcon's Twister Race can be heard in "The Reason," best heard around 2:07. I may be wrong, but this is definitely worth noting.

Also, the drum loop at about 0:13 of "The Devil's Den" sounds very similar to 0:07 of "No More Mr. Nice Guy" by Alice Cooper.
